Hi, I want to change the uart pin definition in programmer_ES5.bin, but I can not find the origin project. Could you please tell me which project is the firmware built from? Thanks.

And what's more, if I have burned the OTP memory and disable the JLINK interface, I can no longer use UART to download firmware to the RAM, am I right?

Hi summer20100514

Hi summer20100514

Check the AN-B-020 doc at paragraph 9.2.1 Uart downloading. You should be able to change uart pin using the included command.

好吧,I have read the doc before, but as far as I am concerned, the command can only select specific UART pins, not a arbitrary one.

You should not download the image to 0x160, but 0x00. Otherwise probably nothing will work.
You can build your own programmer_ES5 from the project flash_programmer in the tools directory in the sdk. You can modify it to use another gpio port/pin and/or baud rate for uart communication.

Thanks for Sharing Joacimwe

Also, yes you are right, after you burn the OTP the serial boot sequence will not be executed anymore.
